In an experiment to measure the thermal conductivity of a plate of unknown material with area 1m2and thickness 0.1m, one of its surfaces is maintained at 100 °C and the other at 20 °C and a heatat the rate of 100 kW was supplied across it. Determine the thermal conductivity of the hot plate. Is the material metallic, non-metallic, or gas/liquid

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
